I would suggest there are ice conditions that will give a bit more friction than in this demo.
Also, different swivel breakouts amongst tailwheel mfgr and riggings may give a different result. Plus any winds and gusts. As we used to say with demonstration flying- only a limits demo will impress pilots. This is a demo for the non-pilot crowd.
That was impressive.
Exempt, but 2016 dues gladly paid!
